Problem Problem 9. Salt Production: Solar evaporation of seawater or salt mining are common methods to produce common salt (NaCl).Propose a method to extract salt from a natural source and determine both productive capacity of your method and purity of the product. Demonstrate an amount of salt produced by your method. Task partially fulfilled 2 IYNT 2017-Team Switzerland
Outline of Report Phenomenon Theory Method Setup Demonstration salt produced Productive Capacity Purity of Salt Experiments Conclusion 3 Good Ok Needs Improvement
Reporter: Strengths and Weaknesses Strengths Interpretation highlighted key words Detailed purification method Attempted to purify salt Experimental method fully shown Weaknesses Didn t experimentally test the purity of the salt Time management Confusing graphs about elements of sea water Confusing equations and not enough time to read them Productive capacity definition not correct Tables used when graphs would have been clearer 4 IYNT 2017-Team Switzerland
